craigten Posted May 10, 2015 Posted May 10, 2015 Hello Im am trying to change the roof type to a gable end on a small building im designing, by dragging the apex as i have read. For some reason it does not work with my drawing. I notice that the roof on my drawing is not fully connected and I can not get a full roof showing on my drawing, can any one help please. Drawing attached Regard Craig Quote
danellis Posted May 10, 2015 Posted May 10, 2015 Roofs do sometime behave strangely - I've no idea why! Will it let you drag the point in or out, changing the steepness of the hip end? Given that it's a fairly simply roof I'd probably redraw the roof, using the GABLE Yes/No commandline switch (truth be told I tend to draw that way to start with, rather than bothering to drag the point out afterwards!) dJE Quote
craigten Posted May 10, 2015 Author Posted May 10, 2015 Hi Danellis It will allow me to drag inwards but not to edge creating gable end. If I try to start with gable command it tries to draw gable on all sides.. ? which makes it more complicated, i would prefer to use gable command but it doest seem that simple unless i have changed a setting somewhere.. Thanks Craig Quote
danellis Posted May 10, 2015 Posted May 10, 2015 The gable commandline switch is something you use within the ROOFADD command to tell ACA that the next stretch of roof either is, or isn't, going to be a gable so working through in sequence: start your ROOFADD in the usual way and set your pitch, overhangs, etc. Pick your first corner Type GABLE (just G will do) Type YES (just Y will do) - this tells ACA that the next stretch of roof will be a gable click on the other end of your gable Type G Type No (just N will do) - this tells ACA that the next stretch of roof will be eaves click on the next corner Type G Type Y - you're starting another gable click on the next corner Type G Type N - to start another stretch of eaves click on the next corner (based on your OP this will be the first point again) HTH dJE Quote
craigten Posted May 10, 2015 Author Posted May 10, 2015 Hi Danellis Thank you for your explaination but i tried 4x with the same result.. no roof, although prior to selecting enter at end it did show a roof but without centre apex (attached jpeg prior to and after finishing roof commands) so something must be setup wrong i guess.. thank you for your time, dont want to waste your time but if you have any other suggestions ill be happy to try.

craigten Posted May 10, 2015 Author Posted May 10, 2015 If you would like to try ive attached the dwg file. Thanks Craig roof drawing.dwg Quote
Cad64 Posted May 10, 2015 Posted May 10, 2015 Since this thread seems to be dealing with commands and procedures that are unique to Autocad Architecture I have moved this thread to the Architecture & ADT section: http://www.cadtutor.net/forum/forumdisplay.php?56-Architecture-amp-ADT Quote
craigten Posted May 11, 2015 Author Posted May 11, 2015 I removed my internal walls and followed your instructions and success.. Thank you for your help Danellis Regards Craig Quote
danellis Posted May 11, 2015 Posted May 11, 2015 Don't understand why removing the internal walls would have fixed it, but I'm glad that worked. I often find that roofs works better if you create a polyline of the footprint, move that off out the way and trace over that to create the roof - this technique also worked for me on your model. (Talking of which, you may want to double check your model: it's not square and a lot of the numbers were "odd" - the one eaves I checked was overhanging by 203.234242mm, for example). dJE Quote
f700es Posted May 11, 2015 Posted May 11, 2015 I just tried this on my Acad-Arch 2015 and there is a setting to toggle gable or not when you create the roof. Might be worth a shot to try that on a test design. Glad you found a work around. Quote
BillGlennie Posted May 15, 2015 Posted May 15, 2015 Slightly irregular geometry can cause the roof object to fail. If you can post a drawing with the roof that does not work properly, we may be able to figure out how to fix this issue. Thank you for your help, Bill Glennie AutoCAD Architecture Team Autodesk, Inc.

BillGlennie Posted May 18, 2015 Posted May 18, 2015 Got it. If you select each of the four outer walls, you'll see in the Properties Palette (Location) that they are slightly off of even angles - about 0.006 to 0.04 degrees. We will investigate this, but if you are interested, here is how to fix the geometry. 1. Set the wall angles to be exact degrees. 2. Select the four walls and pick the Intelligent Cleanup tool from the ribbon. Press [Enter] to run that command. Then redraw the roof, and it will behave normally. Let me know if you have any questions. Thanks, Bill Quote
